Circuit/System Verification
Verify the vehicle is not in the OnStar initiated Stolen Vehicle Slowdown mode. Verify the scan tool ECM Reduced Engine Power History parameter is not Spd Limit Active.
- If the parameter is Spd Limit Active, perform the scan tool VCIM Stolen Vehicle Slowdown Clear. When the Stolen Vehicle Slowdown Clear is complete, press the blue OnStar button and inform the advisor that you need to be transferred to the stolen vehicle team to update the vehicle account.
